Need to know what your dsl sync stats are and more details about the link?
cisco877>sh dsl int
Or as in my case improving the attenuation on the upstream by 3dB..we can modify the gain tx-offset value to 3
Enter exec mode:
cisco877#conf t
cisco877(config)#int atm0
cisco877(config-if)#dsl gain-setting tx-offset 3
To show ppooe uptime on the session:
Look at the active time column
cisco877#sh caller
To show logs on the modem to see activity:
cisco877#sh log
Need to troubleshoot pppoe events, atm, errors, and see more detail, simply issue..
cisco877#debug pppoe events
cisco877#debug pppoe errors
cisco877#debug atm events
cisco877#debug atm errors
These details will then be logged into the log file as above. To remove the debugging simply issue the no statement at the front.
If you have any more tips,hints, recommendations, please comment below 🙂

Warning! a tx-offset will be shown in the stats, but you’re not changing anything. I think you’re liying the router (and you). This could impact in the decisions taken by the router to:
– Increase or lower the power output
– Increase or lower the bits per bin on the DSL spectrum
– Incorrectly show the values of attenuation of the cable
I think it’s not a real good idea to play with tx or rx offsets. I think they are only “offsets” added to the real measurement of the router.
hmm interesting..i did manage to drop the upstream attenuation by 3dB and it improved the upstream upload rate as well
